Questions
How big is the MOSAIC ProtoBoard PCB?
It measures 89 × 89 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MOSAIC ProtoBoard use?
17 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MOSAIC ProtoBoard KiCad files?
From the MOSAIC-Satellite/protoboard repository on GitHub, at the commit this page was made from: the board is ProtoBoard_V1/MOSAIC ProtoBoard.kicad_pcb and its schematic ProtoBoard_V1/MOSAIC ProtoBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MOSAIC ProtoBoard design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
